SPECIFICATION forming part of Letters Patent No. 255,462, dated March 28, 1882.

\ Application filed December 17,1880. (No model.)

To all whom it may concern Be it known that I, BENJ.L. RYDER, of

Chambersburg, Franklin county, Pennsylvania, have invented an Improvement in Porta ble Furnace and Boiler,with a Clothes -Washer Attached; and I do hereby declare the following to be a full and correct description of the 'box on the boiler and a slat bottom or wire basket in the bottom of the boiler. Fig. 3 is a view of my furnace, boiler, and washer combined. Fig. 4 is a vertical longitudinal section of the same on the line 3 y, Fig. 3. Fig. 5 is a transverse section through the machine on the line or 00, Fig. 3. Fig. 6 is a detached view, showing the bar Ofastened to the sides of the wooden box by means of wood-screws, thus holding the sheet-metal sides of the furnace in place.

My invention consists of a novel construction of portable furnace and boiler for various domes ic purposes, having a clothes-washer attached, all of which will be fully understood by the following description and claims.

In the construction of my machine I make a suitable box of plank properly joined and fastened together, supported by legs bolted to the sides, as shown in Fig. 1. This box is usually made with a central cross-partition, B, and a sheet-metal (tin, copper, or galvanized sheet iron) bottom, which is seeurelyfastened on the bottom edge of the wooden sides, and is turned up at both ends and fastened so as to make a perfectly water-tight box or tank, A, the bottom of which forms the top of the furnace D. This furnace and the flue thereof extend the whole length of the boiler, and the former has a flat bottom and wings expanding to the sides of the box A, (so that the fire may fully heat the entire bottom of the boiler,) and also a firedoor in front and the smoke-pipe K in the rear. The front and rear ends are made of cast-iron plates D, which have suitable flanges to receive the sheet-metal wingsor sides of the furnace. These plates have lugs projecting l beyond the sides of the box A and inserted into the legs, or they are otherwise properly supported.

In order to prevent the bottom of the boiler from sagging with the weight of water in the boiler, I fix an iron pipe or tube, E, as a special support, either alone orin combination with an iron bar across the bottom centrally. This pipe or tube is open at both ends, to allow the cold air to pass through and prevent its becoming so hot as to bend. The ends of this pipe are held close to the bottom of the boiler by suitable fastenings on the wood sides of tank or boiler. Cast-iron supporting-bars O are used to fasten the edges of the sheet-metal forming the sides or nings of the furnace to the under side. of the box or boiler. These bars 0 are fastened in place by means of woodscrews 0, which are inserted into the wooden sides of the boiler or box. The sheet-metal sides or wings of the furnace rest upon the bars 0, and are pressed home to the edges of the box by the action of the wood-screws, thus forming 'a simple and complete joint. The sheet-metal sides of the furnace are bent so as to be convex on the inside, as seen in Fig. 5. By this shape the sides of the furnace retreat from the sides of the box or boiler, thus confining the fire chiefly to the central part ofthe bottom of the boiler, and persons clothing is also secure from fire when working at the sides ofthe furnace.

To prevent the water in the second or rear apartment of the boiler-in which the washing apparatus hereinafter described is placedfrom becoming too hot,I placeadrop-damper, G, in the furnace D, (back of the grate,) which lies on the bottom of the furnace when open, and when closed cuts off most of the heat and confines it to the front part of the boiler A. This damper is operated by the crank-handle it outside of the furnace. A double lid, L, is made to fit on either end of the boiler to keep in the steam when in use asa boiler. A hole, (or series of holes,) m, in these lids and closed by a plug or slide, it, is provided for the passage of steam into thebox P, Fig. 2, for steaming feed, renovating feathers, or any similar purpose. For steaming feed on a larger scale a box or tank may be used as long and wide as the whole boiler, havinga perforated or slatted bottom.

A wood-slat bottom, or preferably a galvanized-wire basket, 1), Fig.2, provided with handles,is made to fit loosely into either compartment of the boiler, and is used in eanningfruit to settheglassjarsoreans upouorinto, and for parboiling potatoes, corn on the ear,&c., preparatory to drying, and for convenience in boiling clothes and lifting them out of the boiling suds.

A washing apparatus is shown in Fig. 5 consisting of the frame E, series of octagonal rollers S, and the ribbed boards a. This frame is made to fit into either compartment of the boiler, but is usually used in the rear one.

Working on the concave bed of rollers S,in which bed the clothes are placed, is a convex or half-cylindrical wash-rubber, r, Fig. 5, having slatsf, attached to end pieces, 1'. This rubber has pivots (see Fig. 4) working in slots t in the end pieces, so that the rubber may freely rise and fall, according to theamount of clothes being operated upon. This rubber has aroekingmotion, being worked by lever or handle a in cross-harp, Figs. 4 and 5. 1n removing and replacing the clothes the rubber v is raised from the concave bed and tilted over on the frame B, out of the way of the operator.

I do not limit my invention to the precise construction above described so long as the general plan and advantages are preserved.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a combined portable furnace and boiler, having the same sheet of metal forming the top of the furnace and bottom of the boiler, the removable supporting-bars O, secured to the sides or box of the boiler by means of woodscrews, for the purpose of holding in place the bottom of the boiler or top of the furnace, and also holding the wings or sheet metal forming the sides of the furnace, substantially as and for the purposes set forth.

2. In a combined portable furnace and boiler, having the same sheet of metal forming the top of the furnace and bottom of the boiler, and the removable supporting-bars 0, secured to the sides or box of the boiler by means of wood screws, for the purpose of holding in place the bottom of the boiler or top of the furnaee, and also for holding the wings or sheet metal forming the sides of the furnace, the said sides of the furnace made internally convex and expanding outwardly, whereby the products of combustion are made to pass in a thin sheet under the sides of the boiler, substantially as set forth.

3; In a combined portable furnace and boiler, having the same sheet of metal forming the top of the furnace and bottom of the boiler, and the removable supportingbars O, secured to the sides or box of the boiler by means of wood-screws, for the purpose of holding in place the bottom of the boiler or top of the furnace, and also for holding the wings or sheet metal forming the sides of the furnace, a removable eribhaving a slat bottom and wovenwire sides, the same being fitted to each end of the two-compartment boiler, substantially in the manner and for the purposes set forth.

The above specification of my said invention signed and witnessed, at Washington, this 16th day of December, A. D. 1.880.
